What kind of JTAG this board is using?

Hello, I'm following a tutorial PCB board for Cyclone 4. I'm using the design found here provided by one man has done it before: https://bitbucket.org/avakar/omicron_analyzer/src/00e2960f9...

AFAIK there isn't a JTAG connector pin-out standard. Although the 10-pin configuration used by Altera on the USB Blaster is quite common among different manufacturers, I've also seen some 6 pin variations. You should be able to use it with a USB blaster but you will need to make an adapter cable to connect the different signals to the correct pins.

Dear Daixiwen, by conencting "the different signals to the correct pins", you mean I just connect the pin from his JTAG port to the correct pin of the USB blaster, right?
